Hey if anyone could help me solve this that be awesome :D
Montano1993 [528]
I'm here to help.  Those 3 points all lie on the same line.  We know this because if we find the slope between any 2 of those points, it is the same.  I'll show you: m= \frac{12-20}{15-10}=- \frac{8}{5}.  Now another 2 points: m= \frac{4-12}{20-15}=- \frac{8}{5}.  The same holds for the first and third points.  So we got that out of the way.  Now we will pick any one of those points and use the x and y values and our slope to write an equation of that line and then finally solve for the x and y intercepts.  I'm going to use the first point (10, 20): y-20=- \frac{8}{5}(x-10).  We will simplify to get it into y = mx + b form: y-20=- \frac{8}{5}x+ \frac{80}{5} and y-20=- \frac{8}{5}x+16 and finally, y=- \frac{8}{5}x+36.  The y-intercept exists when x = 0, so when x = 0, y = 36.  The x-intercept exists when y = 0, so when y = 0, x = 22.5.  In summary, y-intercept: (0, 36).  x-intercept: (22.5, 0)  and you're all done!

lesya [120]

Answer:none

You must mean 64 instead of 46.Because 29+20+15=64 but none would agree to dislike both popcorn not peanuts.

Suppose the tank has a vertex angle of 60° and the circular hole has radius 4 inches. Determine the differential equation govern
stepladder [879]

The time it will take the tank to be empty is;

<em><u>t = 1.26 minutes</u></em>

The image of the initial tank is missing and so i have attached it.

Let's call the area of the hole be A_h

  • From conservation of energy, velocity at which water leaves the tank is; v = √2gh

Thus, volumetric rate;  = A_h(√2gh)

  • If we consider possible friction and contraction, we differentiate to get;

dV/dt = -cA_h(√2gh)

Now, volume of tank is;

V = ¹/₃πr²h

V' = dv/dt =  (¹/₃πr²h)dh/dt

Thus; -cA_h(√2gh) = (¹/₃πr²h)dh/dt

  • Integrating to get t gives us;

t = (2(√H - √h))/(3c√2g × (r'/r)²)

where;

r' is radius of circular hole = 4 inches = 0.333 ft

h = 0 since the tank has a hole

c = 0.6

g = 32 ft/s²

H = 8 ft

  • Since the vertex has an angle of 60°, then a line of symmetry across it divides the angle into two which will be 30° each. We can use trigonometry to find the current radius r.

Thus; r/H = tan 30°

r = 8 tan 30°

r = 4.6188 ft

Thus;

t = (2(√8 - √0))/(3 × 0.6(√2 × 32) × (0.333/4.6188)²)

t = 75.5757 seconds

Converting to minutes gives; t = 1.26 minutes
